ISO 12236

This standard specifies a method for the determination of the puncture resistance by measuring the force required to push a flat-ended plunger through geosynthetics. The test is normally carried out on dry specimens conditioned in the specified atmosphere. The test is applicable to most types of products, but not to materials with apertures greater than 10 mm.

Equipment requirement:
The testing machine shall be of class 1 in accordance with ISO 7500-1 and shall be capable of the following:
1)a travel of at least 100mm;
2)a constant rate of travel of (50+/-10)mm/min;
3)recording force and displacement;
4)providing an autographic read-out of force and displacement.
